Be aware that I will ask all those noob questions that I can't seem to find reliable research on but here goes.
I am building a computer and decided to go with
G.SKill 8500 CL5D 4GBPI 8500 4GB (2x2) DDR2 - 1066 CLS 5-5-5-15 240pin Dual Channel Memory
but they ran out at Ncix.com so I saw something else that looked like the exact same memory except for the other memory had 4GBPK it had a K instead of the I and one was more expensive then the other. I'd tell you which but they've been having troubles with the site and nothing is loading up lol.
Otheriwse I know 4GB (2x2) mean two sticks of ram at 2GB a piece, DDR2 I have no idea, 1066 I think is MHz but not sure, CLS 5-5-5-15 is various clock speeds which I'm sure have something to do with overclocking but again not sure, 240pin I imagine is the connecting port. oh and CL5D... no idea what that means
If anyone can answer these innane newb questions then I'm all ears
